Description: TITLE Substituted Caprolactams and Derivatives Thereof Useful for Treatment of HIV Disease Cross-reference to Earlier Filed Application This application is a continuation-in-part of U.S. Patent Application Serial Number 07/965,061, filed October 22, 1992. FIELD OF THE INVENTION This invention relates to novel substituted caprolactams, including 4-azacaprolactams, and derivatives thereof which inhibit HIV protease and are useful for treatment of HIV disease. Also included in this invention are pharmaceutical compositions containing such caprolactams, and to methods of using such caprolactams for the treatment of HIV disease. BACKGROUND OF THE INVENTION Current treatments for viral diseases usually involve administration of compounds that inhibit viral DNA synthesis. Current treatments for AIDS (Dagani, Chem . Eng . News, November 23, 1987 pp. 41-49) involve administration of agents such as 2 ' , 3 '-dideoxycytidine, trisodium phosphonoformate, ammonium 21-tungsto-9- antimoniate, 1-b-D-ribofuranoxyl-l,2, -triazole-3- carboxamide, 3 '-azido-3 '-deoxythymidine (AZT) , and adriamycin that inhibit viral DNA synthesis; compounds such as AL-721 and polymannoacetate which may prevent HIV from penetrating the host cell; and compounds which treat the opportunistic infections caused by the immunosupression resulting from HIV infection. None of the current AIDS treatments have proven to be totally effective in treating and/or reversing the disease. In addition, many of the compounds currently used to treat AIDS cause adverse side effects including low platelet count, renal toxicity, and bone marrow cytopenia. Proteases are enzymes which cleave proteins at specific peptide bonds. Many biological functions are controlled or mediated by proteases and their complementary protease inhibitors. For example, the protease renin cleaves the peptide angiotensinogen to produce the peptide angiotensin I. Angiotensin I is further cleaved by the protease angiotensin converting enzyme (ACE) to form the hypotensive peptide angiotensin II. Inhibitors of renin and ACE are known to reduce high blood pressure in vivo . However, no therapeutically useful renin protease inhibitors have been developed, due to problems of oral availability and in vi vo stability. The genomes of retroviruses encode a protease that is responsible for the proteolytic processing of one or more polyprotein precursors such as the pol and gag gene products. See ellink, Arch . Virol . ___ϋ 1 (1988) . Retroviral proteases most commonly process the gag precursor into the core proteins, and also process the pol precursor into reverse transcriptase and retroviral protease . The correct processing of the precursor polyproteins by the retroviral protease is necessary for the assembly of the infectious virions . It has been shown that in vi tro mutagenesis that produces protease- defective virus leads to the production of immature core forms which lack infectivity. See Crawford et al., J. Virol . ____i 899 (1985); Katoh et al . , Virology IAS. 280 (1985) . Therefore, retroviral protease inhibition provides an attractive target for antiviral therapy. See Mitsuya, Nature 225. 775 (1987) . Moore, Bioche . Biophys . Res . Commun . , 159 420 (1989) discloses peptidyl inhibitors of HIV protease. Erickson, European Patent Application No. WO 89/10752 discloses derivatives of peptides which are inhibitors of HIV protease. U.S. Patent No. 4,652,552 discloses methyl ketone derivatives of tetrapeptides as inhibitors of viral proteases. U.S. Patent No. 4,644,055 discloses halomethyl derivatives of peptides as inhibitors of viral proteases. European Patent Application No. WO 87/07836 discloses L-glutamic acid gamma- monohydroxamate as an antiviral agent. Japanese Patent Number 02306992 and Kimura, Agric . Biol . Chem . , 5_3_ . 1811 (1989) describe compounds of the formula: wherein R is a fatty acid. These compounds were isolated from streptomyces and shown to be useful as peptidoglycan inhibitors. French Patent Number 2396002 describes quaternary amines, of the formula shown below, which are useful as vasodilators : wherein R~ is hydrogen or ester and R^ is C1-C2 alkyl. The ability to inhibit a viral protease provides a method for blocking viral replication and therefore a treatment for viral diseases, such as AIDS, that may have fewer side effects, be more efficacious, and be less prone to drug resistance when compared to current treatments . The topic of the present invention is substituted caprolactams and derivatives thereof, which compounds are capable of inhibiting HIV protease and are, therefore, useful for combating HIV diseases, such as AIDS. The caprolactams and derivatives thereof of this invention provide significant improvements over protease inhibitors that are known in the art . A large number of compounds have been reported to be inhibitors of proteases, such as renin, but these have suffered from lack of adequate bioavailability and are thus not useful as therapeutic agents, particularly if oral administration is desired. This poor activity has been ascribed to the relatively high molecular weight of most protease inhibitors, to inadequate solubility properties, and to the presence of a number of peptide bonds, which are vulnerable to cleavage by mammalian proteases in vivo and which generally cause the molecules to be extensively bound in human serum. The substituted caprolactams and derivatives thereof of the present invention and described herein have a distinct advantage in this regard, in that they do not contain -4- SUBSΠTUTESHEET(RULE26) peptide bonds, are of low molecular weight, and can be hydrophilic yet still inhibit the viral protease enzyme. The structures disclosed also have a particular advantage in the presence of a basic amine in the ring; which provides good in vitro potency and aids in formulation, in vivo absorption and CNS penetration of the compound. The substituted caprolactams of the present invention are particularly useful as inhibitors of HIV protease and similar retroviral proteases. The compounds of the invention are of low molecular weight and may, therefore, have good oral absorption properties in mammals.

D.C. Roberts and F. Vellaccio provide a comprehensive listing of unnatural amino acids, and techniques for the synthesis of many variations thereof .The Peptides, Vol. 5: Analysis. Synthesis. Bioloσv. Academic Press, NY, 1983] . A more recent description of additional routes to chirally pure unnatural amino acids is found in Cintas, P. Tetrahedron, 47(32), 6079-111, 1991. Thus, one skilled in the art can synthesize the amino acid precursors used in the preparation of the compounds of the invention by a judicious selection of one or more of the methods outlined above. Each of the references cited herein are hereby incorporated by reference. The substituent R 4 is chosen first, and the corresponding amino acid III with the desired stereochemistry is synthesized or purchased as necessary: III wherein R 4 has the meaning designated above. If substituents on R 4 are deemed to be sensitive to the reaction conditions employed in the following steps, then appropriate protecting groups are used, and the desired substituents are freed from protection at the end of the sequence. Extensive descriptions of the correct choice of protecting groups for various reaction conditions, and the correct method of removal, are described in T.W. Greene and P.G.M. Wuts, Protec ive Groups in Organic Synthesis. 2nd Edition, Wiley, New York, 1991. A protecting group is also chosen for the amine terminal of amino acid III. For example, the above reference can be used to assist the choice of protecting group, or M. Bodanzky and A. Bodanzky in The Practice of Peptide Synthesis. Springer-Verlag, Berlin, 1984 can be consulted. A preferred amine protecting group is the N- carbobenzyloxy (CBZ) group. In the following structures, a protecting group is designated PG. IV The protected amino acid is then converted to the protected amino epoxide by known techniques, such as the Wittig or Petersen olefination of a protected amino aldehyde followed by epoxidation of the olefin; or by addition of a methylene sulfur ylide to an amino aldehyde or by the following, preferred method: treatment of the protected amino acid with diazomethane to generate the diazoketone, followed by treatment with aqueous hydrochloric acid to generate the chloroketone, followed by reduction with a hydride reducing agent, preferably a metal borohydride to form the chloroalcohol. Stereochemistry of the hydroxyl group can be controlled by the choice of reducing agent; preferably a mixture can be obtained which can optionally be separated by chromatography and each -127- SUBST1TUTESHEET(RULE26) diastereomer can be evaluated independently. This step is followed by base-catalyzed elimination of hydrogen chloride in an aprotic solvent, preferably potassium tert-butoxide in tetrahydrofuran, to form the protected amino epoxide V. HCl, H 2 0 I KO l Bu Next the desired R 27 substituent is chosen, with the desired stereochemistry, and the appropriate acid is synthesized or purchased. Protecting groups are added as necessary to the functionality on R 27 . The acid terminus is protected, preferably with the t-butyl ester, to form compound VI: -128- SUBSCTTUTE SHEET (RULE 26) V I V and VI are coupled in the presence of a solvent, preferably methanol, at a temperature between 0 and 100°C, to form the amino alcohol VII: VII The hydroxyl group of VII is protected, preferably with a silyl protecting group such as t-butyldimethylsilyl (TBDMS) chloride. The selected protective group must withstand the conditions used to remove the nitrogen and carboxy protecting groups. The wide variety of protecting groups described in the references above make the selection of the proper combination of groups straightforward to one skilled in the art . The amine and acid protecting groups are removed to form amino acid VIII : -129- SUBSCTTUTE SHEET (RULE 26) which depending on cleavage conditions used may be isolated as a salt of the amines. VIII is cyclized to the lactam IX: any number of standard conditions can be used to form lactams, although the preferred procedure involves activating the carboxylate with a group such as dicylohexylcarbodiimide under conditions dilute enough to favor intramolecular condensation. IX Intermediate IX can be deprotected to form hydroxy lactam X. In instances where the protecting group is TBDMS, the preferred cleavage conditions are tetra-n- butylammonium fluoride in tetrahydrofuran. When R 4 and R 27 are benzyl, X is Example 1. Other representative compounds of the invention are listed in Table 1. Alternatively, IX can be further modified to add substituents R 7 and R 22 . Beginning with the protected alcohol, using methods known to one skilled in the art one may alkylate either the amide nitrogen or the basic nitrogen with a group R 22 -LG or R 7 -LG, respectively, where LG is a leaving group. If alkylation of the basic nitrogen is desired while keeping the amide nitrogen unsubstituted, it is advantageous to protect the amide nitrogen using one of the many protective groups discussed in the above references . A preferred protecting group is benzyl, which can be selectively removed from the basic nitrogen by hydrogenolysis. For obtaining compounds with R 7 ≠ hydrogen and R 22 = hydrogen, the preferred method is to treat IX with a base, such as potassium carbonate, in a polar aprotic solvent, such as dimethylformamide, and add to the mixture between 0 and 100°C an alkylating agent R 7 -LG, preferably an alkyl chloride, bromide iodide, or tosylate. Preferred alkylating agents are substituted benzyl chlorides, substituted Cι-C ~ alkyl bromides, (heterocyclic)methyl chlorides and substituted (alicyclic)methyl bromides and tosylates. -131- SUBST1TUTE SHEET (RULE 26) I X X I If compounds wherein R 22 = R 7 ≠ hydrogen are desired, the preferred method is that described in the preceding paragraph, but substituting a stronger base, preferably sodium hydride, for potassium carbonate and employing 2 equivalents alkylating agent. If R 7 ≠ R 22 , the product XI can be further alkylated in the same fashion to give XII, by substituting a stronger base, preferably sodium hydride, for potassium carbonate and employing 1 equivalent alkylating agent R 22 -LG. Preferred alkylating agents are as described above. X I XI I For the case in which R 22 ≠ H and R 7 = H, as exemplified in XIII, a preferred method is one in which the above procedures are followed, such that IX is first alkylated with benzyl bromide in dimethylformamide (DMF) in the presence of postassium carbonate; the material is purified and subjected to R 22 -LG in the presence of sodium hydride in DMF to give Xlla; after which the N- benzyl is removed by catalytic hydrogenation or preferably by transfer hydrogenation, e.g. formic acid and palladium on carbon in methanol. Xlla XIII (R 7 = CH2Ph) The protecting group on XI-XIII is removed to give removed structure XIV, where Z = 0 as described above. The representative compounds of the invention listed in Table 1 can be prepared by these methods. XIV By the proper manipulation and choice of protecting groups by one skilled in the art, compounds of the formula II, wherein X is S or 0, can be obtained by substitution of a suitably protected form of acid Via in the above described sequences. Further modification of these compounds are detailed above. Via The preferred compounds are those in which Z = 0; however, standard techniques can be employed to convert the carbonyl oxygen to sulfur or an amidine or substituted amidine. These techniques are described in detail in copending application U.S. Patent Application 07/883,944, filed May 15, 1992, which is incorporated by reference . The preferred compounds are those in which R 4a and R 2 ^ are hydrogen. However, compounds in which R a and R 2 ^ are substituted benzyl or substituted lower alkyl can be prepared by choosing alpha, alpha '-substituted amino acids as starting materials. For example, if, in structure III, the alpha hydrogen is replaced by substituted benzyl or substituted lower alkyl, then the product derived from the synthesis described herein is XV: -134- SUBSCTTUTE SHEET (RULE 26) XV and if in structure VI the alpha hydrogen is replaced by substituted benzyl or substituted lower alkyl then the product of the above-described sequence is XVI. These alpha, alpha' substituted amino acids can be prepared by the means described in the references above, and by other means well known to skilled in the art of organic synthesis . XVI Compounds in which the side chains on the same side of the seven-membered ring are joined to form a fused ring are contemplated as part of this invention. Specifically, compound XVII can be formed by choosing amino acid VI such that R 27 is protected 4-hydroxybutyl (n=2) or protected 3-hydroxypropyl . Release of the hydroxy group, conversion to the tosylate or mesylate in dilute solution in a polar aprotic solvent at 0-100°C in the presence of a weak base will result in the fused ring system. XVII If a similar procedure is employed with R 4 , and the resulting tosylate or mesylate is heated in dilute solution with a stronger base such as sodium hydride in a polar aprotic solvent, the fused ring system XVIII can be obtained. XVIII The absolute and relative stereochemistry of the ring substituents are important for the degree of binding of these compounds to the HIV protease active site. Although a preferred diastereo er is shown in -136- SUBSCTTUTE SHEET (RULE 26) structure XIX, other diastereomers are also active and are contemplated as part of this invention. Control over stereochemistry is obtained by choice of starting materials III and VI, and by choice of reducing agent to form chloroalcohol as described above. XIX Other compounds of this invention can be prepared as outlined by the schemes below, using the methods and procedures described herein, or additionally, the methods and procedures described in US Patent Application No.USSN 08/023,439, filed 2/26/93. The compounds of the general formula XX can be prepared as shown in Scheme 1. The compound of the general formula XXa and XXc can be prepared according to the method described by A. S. Dutt and J. S. Morley (J. Chem. Soc. Perkin I. 1712, (1975)) . Treatment of XXa with 1 equivalent of ethylene oxide would provide intermediate XX (where R = H) which can be activated to XXb (where R = mesylate or tosylate) by methods well known to the skilled in the art. The resulting intermediate then heated in solvents such as methanol, ethanol, etc. in the presence of XXc to provide XXd. The compound XXe could be obtained by treatment of XXd with acids such as trifluoroacetic acid or hydrochloric acid in a suitable solvent. The intermediate XXe can be -137- SUBST1TUTE SHEET (RULE 26) cyclized to XXf by treatment with carbonyldiimidazole (CDI) and then alkylated with sodium hydride to give the desired XXg (where R 22 = R 2 ^) . The compounds of general formula XXI can be prepared as detailed in Scheme 2. Hydrazine XXIa (EP 521827 A) is treated with triethylsilyl chloride according to the method of Corey et al. (J. Am. Chem. Soc. , 1971, 93, 7319), followed by aqueous hydrolysis, to give XXIb. Carbonyl diimidazole cyclization followed by alkylation under the standard procedure gives XXId. Deprotection by HCl/MeOH yields XXIe. As further detailed in Scheme 2 continued, XXIf is treated with KCN followed by protection, Dibal-H reduction to give XXIg, and further reaction with hydrazine to provide XXIi. XXIi could be reacted with C1C(=0)C1 (phosgene), followed by treatment with triethylamine to give XXIk which can be cyclized to XXII by heating in toluene. Following the same alkylation & deprotection procedures as described previously, the desired XXIe can be obtained. The compounds of general formula XXIII are shown in Scheme 4. Compound XXIIIa (T. Minoto, et al . EP 0490667A2; Y. Yabe, et al . EP 0498680A; R. Herranz, et al. J. Org. Chem., 1990, 55, 2232) was protected as the THP ether and the methyl ester hydrolyzed to give XXIIIb, which was coupled with O-benzyl phenylalanine using 1, 3-dicyclohexylcarbodiimide (DCC) . Hydrogenolysis of the O-benzyl group and phenylmethoxycarbonyl (CBZ) protecting groups would give XXIIId, which was then cyclized with DCC to give XXIIIe. Standard alkylation was performed to give XXIIIf, which was then hydrolyzed in acidic medium to give the desired XXIIIg. XXIV Any of the compounds of formula XXIV described in Scheme 5 can be derived from the joining of an amino acid derivative and a hydroxy-protected statine derivative, followed by elaboration of substituents as necessary. Natural amino acids are available in abundance, and a great array of unnatural amino acids have been prepared by techniques well known to those skilled in the art of organic synthesis. D.C. Roberts and F. Vellaccio provide a comprehensive listing of unnatural amino acids, and techniques for the synthesis of many variations thereof. .The Peptides. Vol. 5: Analysis. Synthesis, Biology; Academic Press, NY 1983. A more recent description of additional routes to chirally pure unnatural amino acids is in: Asymmetric synthesis of .alpha.-amino acids from carbohydrates as chiral templates; Cintas, P. Tetrahedron. 1991, 47(32), 6079- 111. Thus one skilled in the art can synthesize the amino acid precursors used in the preparation of the compounds of the invention by a judicious selection of one or more of the methods outlined above, which articles are hereby incorporated by reference. Statine derivatives are also well known in the literature and can be prepared by methods disclosed in EP 0 401 675 Al . Other methods are described in the series cited above (The Peptides. Vol. 5: Analysis. Synthesis. Biology; -139- SUBST1TUTE SHEET (RULE 26) Academic Press, NY 1983] and by Bringmann et al. in Synlett (5), 253-255 (1990); by Kessler and Schudok in Synthesis (6) 457-8 (1990); and by Nishi and Morisawa in Heterocycles 29(9), 1835-42 (1989) . The statine hydroxyl is protected if necessary; the preferred protecting group is tert-butyldimethylsilyl . The amino acid is protected at the carboxyl group, the statine derivative is protected at the amino group, and the amide bond is formed using techniques described in the references. The preferred N-protecting group is phenylmethoxycarbonyl (CBZ) , the preferred carboxylic acid protecting group is tert-butyl ester, and the preferred coupling reagent is 1,3- dicyclohexylcarbodiimide . The product XXIVc is isolated and purified if necessary, and protecting groups are removed by standard methods; if the preferred groups are employed, the CBZ protecting group is removed by treatment with 10% palladium on carbon in the presence of ethanol, tetrahydrofuran and hydrogen gas, or by the action of palladium oxide in ethanol/water in the presence of cyclohexene. The preferred t-butyl ester is removed with 25% triflouracetic acid in dichloromethane . These steps yield XXIVd. Compound XXIVd is cyclized using standard techniques to XXIVe. Dicyclohexylcarbodiimide is the preferred cyclization reagent. The amide nitrogens are alkylated if desired; the preferred alkylating agents are benzylic or allylic bromides, or alkyl iodides or tosylates, in the presence of sodium hydride in an aprotic solvent . One or two alkyl groups can be provided depending on the stoichiometry of the alkylating agent and base . Removal of the hydroxyl protecting group using standard conditions, preferably tetra-n-butyl ammonium flouride, yields the desired product XXIV. -140- SUBSΠTUTESHEET(RULE26) Compounds of the general formula XXVI can be synthesized using Scheme 7. Norstatin, XXVIa can be hydrogenated to remove CBZ protecting group and the resulting amine can be reprotected using t- butoxycarbonyl (BOC) . p-Methoxyphenylmethyl protecting groups are alkylated on both the alcohol and acid; afterwhich basic hydrolysis yields XXVIb. Condensation with t-butyl 2-benzylcarbazate (A.S. Dutta and J.S. Morley, J. Chem. Soc. Perkin I, 1975, 1712) was facilitated using DCC. The BOC group can be removed using acid conditons and the resulting diamine cyclized with carbonyldiimidazole to give XXVId. Alkylation as previously described, deprotection using dichlorodicyanobenzoquinone (DDQ) followed by HCl/MeOH will yield XXVIf. Sequential alkylation with different alkylating agents can also be performed. The compounds of the present invention may be prepared using methods known in the art of organic synthesis. The compounds may be synthesized, for example, in accordance with the synthetic schemes set forth below. -141- SUBSCTTUTE SHEET (RULE 26) Scheme 1 NHBoc I XXc BocNH V ocHN HN.

HPLC measurement of product formation: The product (aminobenzoyl-Ala-Thr-His-Gln-Val-Tyr) was separated from substrate on a Pharmacia MonoQ anion exchange column. The injection volume was 200 ul . The mobile phases were: A (20 mM trisHCl, pH 9.0, 0.02% sodium azide, 10% acetonitrile) , B (20 mM tris HCl, pH 9.0, •0.02% sodium azide, 0.5 M ammonium formate, 10% acetonitrile) . The mobile phases were pumped at 1 ml/min, with a gradient from 0 to 30% B in 5 min, 100 % B for 4 min to wash the column, and a re-equilibration for 4 min. The retention time of the product was 3.6 min. Detection with a Shimadzu model RF535 fluorescence monitor was at 330 nm (excitation) and 430 (emission) . The Ki was calculated from the formula Ki = 1/ ( ( (Km+S- FA*S) / (FA*Km) )-l) where I = inhibitory concentration, S = substrate concentration, FA = fractional activity = cm peak height with inhibitor/cm peak height without inhibitor, and Km = Michaelis constant = 20 uM. HIV Yield Reduction Cell Assay Materials: MT-2, a human T-cell line, was cultured in RPMI medium supplemented with 5% (v/v) heat inactivated fetal calf serum (FCS) , L-glutamine and gentamycin. Human immunodeficiency virus strains, HIV (3B) and HIV(RF) were propagated in H-9 cells in RPMI with 5% FCS. Poly-L-lysine (Sigma) coated cell culture plates were prepared according to the method of Harada et al. (1985) Science 229: 563-566. MTT, 3-(4,5- dimethyl-thiazol-2yl) -2, 5-diphenyltetrazolium bromide, was obtained from Sigma. Method: Test compounds were dissolved in dimethylsulfoxide to 5 mg/mL and serially diluted into RPMI medium to ten times the desired final concentration. MT-2 cells (5 x 10^/mL) in 2.3 mL were mixed with 0.3 ml of the appropriate test compound solution and allowed to sit for 30 minutes at room temperature. HIV (3B) or HIV (RF) (~5 x 10 5 plaque forming units/mL) in 0.375 ml was added to the cell and compound mixtures and incubated for one hour at 36°C. The mixtures were centrifuged at 1000 rpm for 10 minutes and the supernatants containing unattached virus were discarded. The cell pellets were suspended in fresh RPMI containing the appropriate concentrations of test compound and placed in a 36°C, 4% Cθ2 incubator. Virus was allowed to replicate for 3 days. Cultures were centrifuged for 10 minutes at 1000 rpm and the supernatants containing cell free progeny virus were removed for plaque assay. The virus titers of the progeny virus produced in the presence or absence of test compounds were determined by plaque assay. Progeny virus suspensions were serially diluted in RPMI and 1.0 mL of each dilution was added to 9 ml of MT-2 cells in RPMI. Cells and virus were incubated for 3 hours at 36°C to allow for efficient attachment of the virus to cells. Aliquots of each virus and cell mixture were added equally to two wells of a six well poly-L-lysine coated culture plate and incubated overnight at 36°C, 4% CO2. Liquid and unattached cells were removed prior to the addition of 1.5 mL of RPMI with 0.75% (w/v) Seaplaque agarose (FMC Corp.) and 5% FCS. Plates were incubated for 3 days and a second RPMI/agarose overlay was added. After an additional 3 days at 36°C, 4% CO2, a final overlay of phosphate-buffered saline with 0.75% Seaplaque agarose and 1 mg MTT/mL was added. The plates were incubated overnight at 36°C. Clear plaques on a purple background were counted and the number of plaque forming units of virus was calculated for each sample. The antiviral activity of test compounds was determined by the percent reduction in the virus titer with respect to virus grown in the absence of any inhibitors. -164- SUBSTJTUTESHEET(RULE26) HIV Low Multiplicity Assay Materials: MT-2, a human T-cell line, was cultured in RPMI medium supplemented with 5% (v/v) heat inactivated fetal calf serum (FCS) , L-glutamine and gentamycin (GIBCO) . Human immunodeficiency virus strains HIV (3B) and HIV (RF) were propagated in H-9 cells in RPMI with 5% FCS. XTT, benzene-sulfonic acid, 3, 3 '- [1- [ (phenyl-amino)carbonyl]-3, 4-tetrazolium]bis (4- methoxy-6-nitro) -, sodium salt, was obtained from Starks Associates, Inc. Method: Test compounds were dissolved in dimethyl- sulfoxide to 5 mg/ml and serially diluted into RPMI medium to ten times the desired final concentration. MT-2 cells (5 x lθVθ.1 mL) were added to each well of a 96 well culture plate and 0.02 mL of the appropriate test compound solution was added to the cells such that each compound concentration was present in two wells. The cells and compounds were allowed to sit for 30 minutes at room temperature. HIV(3B) or HIV(RF) (-5 x 10- > plaque forming units/mL) was diluted in medium and added to the cell and compound mixtures to give a multiplicity of infection of 0.01 plaque forming unit/cell. The mixtures were incubated for 7 days at 36°C, during which time the virus replicated and caused the death of unprotected cells. The percentage of cells protected from virus induced cell death was determined by the degree of metabolism of the tetrazolium dye, XTT. In living cells, XTT was metabolized to a colored formazan product which was quantitated spectrophotometrically at 450 nm. The amount of colored formazan was proportional to the number of cells protected from virus by the test compound. The concentration of compound protecting either 50% (IC 50 ) or 90% (IC 9Q ) with respect to an uninfected cell culture was determined. The HIV inhibitory activity of representative compounds of the present invention in the whole cell infectivity assay described above is shown in Table 2. Table 2 Example Number Ki XQ90 l +++ +++ 24 ++ +++ The IC 9 Q values in Table 2 are indicated as: +++ = <10 ug/mL. In the Tables herein the Ki values were determined using the assay conditions described above under HIV Protease Inhibition Assay-HPLC Method. The Ki values are indicated as follows: +++ = <10 nM; ++ = 10 nM to 1 uM; + = >1 uM. In the Tables herein the IC 9 o values were determined using the assay conditions described above under HIV Low Multiplicity Assay. The IC 9 o values are indicated as follows: +++ = <10 ug/mL; ++ = 10 to 100 ug/mL; + = >100 ug/mL. Dosage and Formulation The antiviral compounds of this invention can be administered as treatment for viral infections by any means that produces contact of the active agent with the agent's site of action, the viral protease, in the body of a mammal. They can be administered by any conventional means available for use in conjunction with pharmaceuticals, either as individual therapeutic agents or in a combination of therapeutic agents. They can be administered alone, but generally administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice. The dosage administered will, of course, vary depending upon known factors, such as the pharmacodynamic characteristics of the particular agent and its mode and route of administration; the age, health and weight of the recipient; the nature and extent of the symptoms; the kind of concurrent treatment; the frequency of treatment; and the effect desired. A daily dosage of active ingredient can be expected to be about 0.001 to 1000 milligrams per kilogram of body weight, with the preferred dose being 0.1 to about 30 mg/kg. Dosage forms (compositions suitable for administration contain from about 1 milligram to about 100 milligrams of active ingredient per unit. In these pharmaceutical compositions the active ingredient will ordinarily be present in an amount of about 0.5-95% by weight based on the total weight of the composition. The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets, and powders, or in liquid dosage forms, such as elixirs, syrups, and suspensions. It can also be administered parenterally, in sterile liquid dosage forms. Gelatin capsules contain the active ingredient and powdered carriers, such as lactose, starch, cellulose derivatives, magnesium stearate, stearic acid, and the like. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of hours. Compressed tablets can be sugar coated or film coated to mask any unpleasant taste and protect the tablet from the atmosphere, or enteric coated for selective disintegration in the gastrointestinal tract. Liquid dosage forms for oral administration can contain coloring and flavoring to increase patient acceptance. In general, water, a suitable oil, saline, aqueous dextrose (glucose) , and related sugar solutions and glycols such as propylene glycol or polyethylene glycols are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents such as sodium bisulfite, sodium sulfite, or ascorbic acid, either alone or combined, are suitable stabilizing agents. Also used are citric acid and its salts and sodium EDTA. In addition, parenteral solutions can contain preservatives, such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol . Suitable pharmaceutical carriers are described in Remington's Pharmaceutical Sciences. Mack Publishing Company, a standard reference text in this field. Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows : Capsule? A large number of unit capsules are prepared by filling standard two-piece hard gelatin capsules each with 100 milligrams of powdered active ingredient, 150 milligrams of lactose, 50 milligrams of cellulose, and 6 milligrams magnesium stearate . Soft Gelatin Capsules A mixture of active ingredient in a digestable oil such as soybean oil, cottonseed oil or olive oil is prepared and injected by means of a positive displacement pump into gelatin to form soft gelatin capsules containing 100 milligrams of the active ingredient. The capsules are washed and dried. Tablets A large number of tablets are prepared by conventional procedures so that the dosage unit was 100 milligrams of active ingredient, 0.2 milligrams of colloidal silicon dioxide, 5 milligrams of magnesium stearate, 275 milligrams of microcrystalline cellulose, 11 milligrams of starch and 98.8 milligrams of lactose. Appropriate coatings may be applied to increase palatability or delay absorption.
